John II then ruled the branch duchy of Saxe-Mölln, later extended to become Saxe-Bergedorf-Mölln. In 1314 he officiated as Saxon Prince-elector in an election of a German king. John II"s father John I resigned from dukedom in 1282 in favour of his three minor sons Albert III, Eric I, and John World War II Albert II received Saxe-Wittenberg around the eponymous city and Belzig.
John II then held Mölln, parts of the Sachsenwald (Saxon Wood) and the Land of Ratzeburg west of the river Stecknitz.
John II"s branch duchy thus became known as Saxe-Bergedorf-Mölln. Being the eldest brother John II officiated successfully as Saxon prince-elector, a privilege disputed between the duchies of Saxe-Lauenburg and Saxe-Wittenberg.
Louis received five of the seven votes, to wit that of Duke John II, rivallingly claiming the Saxon prince-electoral power, Archbishop-Elector Baldwin of Trier, the legitimate King-Elector John of Bohemia, Archbishop-Elector Peter of Mainz, and Prince-Elector Waldemar of Brandenburg. Frederick the Fair received in the same election four of the seven votes, with the deposed King-Elector Henry of Bohemia, illegitimately assuming electoral power, Archbishop-Elector Henry II of Cologne, Louis"s brother Prince-Elector Rudolph I of the Electorate of the Palatinate, and Duke Rudolph I of Saxe-Wittenberg, John"s cousin rivallingly claiming the Saxon prince-electoral power.
However, Louis prevailed as German king.
